Banana Pi BPI-F3

Building

  1. Install the SpacemiT riscv cross compile toolchain, or skip it if riscv toolchain is installed.

  1. Setup cross compilation environment variable:

export CROSS_COMPILE=<riscv64 toolchain prefix, e.g /opt/spacemit/bin/riscv64-unknown-linux-gnu->

3. Before building U-Boot, OpenSBI should be built first. OpenSBI can be built for SpacemiT K1 SoC as below:

git clone https://github.com/cyyself/opensbi -b k1-opensbi
cd opensbi
make PLATFORM=generic

  1. Then build U-Boot as following:

cd <U-Boot-dir>
make bananapi-f3_defconfig
make OPENSBI=<OpenSBI-dir>/build/platform/generic/firmware/fw_dynamic.bin

This will generate u-boot.itb

Burning

Actually, we can replace the uboot partition of Bianbu Linux which is the bsp to validate this patch, use balena etcher to burn the bianbu-minimal.img to the sd card, and replace the /dev/sdx4 where places the uboot with the u-boot.itb generated from this patch. Or use fastboot: Collect FSBL.bin, u-boot.itb, partition_2M.json, bootinfo_spinor.bin u-boot-env-default.bin, fw_dynamic.itb from vendor SDK

fastboot stage FSBL.bin
fastboot continue
fastboot stage u-boot.itb-vendor # the itb from vendor uboot
fastboot continue

fastboot flash mtd partition_2M.json
fastboot flash bootinfo bootinfo_spinor.bin
fastboot flash fsbl FSBL.bin
fastboot flash env u-boot-env-default.bin
fastboot flash opensbi fw_dynamic.itb

fastboot flash uboot u-boot.itb-mainline # the itb from mainline uboot
